Short Communication Pre-Late Devensian high-arctic marine deposits in SW Scotland

摘要

We present new interpretations of Digital Elevation Model (DEM) data and marine fossilscollected from three sites on the Rhins of Galloway which, contrary to recent proposals,suggest that the landforms and deposits of the region do not represent evidence for areadvance during the Lateglacial Period. Rather we suggest that the high-arctic fauna found inthe region are representative of an earlier, colder part of a Middle Devensian ice-free interval.The predominantly streamlined topography, and distinct lack of identifiable discrete morainelimits argues for only minor, local glacial advances, in combination with widespread rapidretreat across the peninsula at the end of the Lateglacial.
